Intradural intervertebral disc herniation in a 5‐year‐old dachshund

A 5‐year‐old male neutered dachshund presented dragging his right hindlimb with a history of acute onset, progressive, non‐painful paraparesis. The lesion was localised to a T3–L3 myelopathy, and MRI revealed moderate spinal cord compression at the L3–L4 intervertebral disc space, which was consistent with intervertebral disc extrusion. A routine hemilaminectomy was performed; however, no compressive material could be located compressing the spinal cord. The surgical site and images were reassessed, but were found to be correct and appropriate. A durotomy was performed and calcified disc material bulged out through the incision, with more fibroid material removed through gentle probing. The site was fenestrated and closed routinely, and the dog was ambulatory the next day and discharged two days later. At re‐examination four weeks later, the dog was ambulatory with no paresis.
